An
experiment was conducted to evaluate the morphological characters of maize
genotypes at Horticultural Research Station, Dailekh in two consecutive years
(2016 and 2017). Altogether, seven genotypes consisting of BGBY POP, BLSPRSO7,
Across 9942/9944, Across 9331/RE, TLBRSO7 along with check varieties (Deuti and
Local) were experimented. The trial was laid out in Randomized Complete Block
Design with three replicates. Data on morphological parameters and yield
attributing traits were recorded. The results over the years of experiment
revealed significant differences for days to maturity, plant height, ear
height, number of kernel per row and grain yield. Furthermore, highest grain
yield was recorded in Across 9944/9942 (7.24 tha^-1) followed by
BLSPRSO7 (6.73 tha^-1). Similarly, number of kernel per row was maximum
in Across 9942/9944 (37.6) followed by Deuti (37.1). The significant variation
in ear height was observed which ranged from 125.4 cm (Across 9944/9942) to 146
cm (local variety). It showed local variety to be early maturing (114 Days After
Sowing); however, Across 9942/9944 was late maturing (119 DAS). Correlation
analysis revealed that ear population, plant population and plant height were
yield determinative and simultaneous selection for these traits might bring an
improvement in grain yield. This study revealed that Across9931/RE can be a
potential genotype for yield and for further maize breeding program.
